2007 forester base X Sitting in very heavy traffic the alternator and parking break light came on at the same time, this is the first time ever seeing this light and I’ve never had any issues with the battery or charging. Rather than mess around I put in a new battery, new alternator and a new belt. The lights still on. With the car off I’m 12.4v at the battery with the car on it drops to 12v. Ugh, I removed, cleaned and all the ground wires with the same results. No idea where to look next
